Does ZRTP work with the Asterisk PBX? What about IAX?

ZRTP has been successfully integrated into Asterisk, an open source PBX server from Digium. This modified version of Asterisk supports ZRTP in SIP/RTP calls, and we are working with Digium to make it available in their Asterisk products. ZRTP has protocol features specially designed to allow a PBX to act as a trusted man-in-the-middle. For more information on ZRTP support for Asterisk SIP/RTP calls, see our Asterisk support page. However, ZRTP and IAX (Inter-Asterisk eXchange protocol) are not well suited for each other in their present forms. Perhaps I’ll have a look at IAX more closely to see what can be done to improve its security.
